question re sensitivity of early pg test

background info :i've been having sharp twinges for days and had slight bleeding yesterday which has stopped. am due on in 3 days. to bleed 4 days early is unheard of for me. am regular as clockwork.

i tested on saturday (too early) with first response, then today with a chemist's own brand early test, but didnt use the frist urine of the day, as it said i should

now, i know i'm being a foolish over this testing business, but would there be any point in going and buying a first response test today?(as i feel the the one i just did 'doesnt count' as i didnt use first urine). am i right in thinking that you dont have to use first urine of the day with first response?

I didnt get a positive until a week after I was due, something to do with me having a late implantation, something like that lol so dont be too put off if you still get a negative (I tested with clear blue)

The most likely reason to bleed slightly before or around the time you were due on is implantation, I only had it with one of my three and it was a tiny amount of blood but same as you I had a bit of twinging for a day or so before. As I hadn't had a period yet since having dd I assumed it was returning but when the period never got going and I started getting preg symptoms.....
